REGISTER FOR GRAIN-MEASURES.

SPECIFICATION forming part of Letters Patent No. 473,465, dated April26, 1892.

Application filed June 3,1891.

To .fz/ZZ whom, t may concern.-

Be it known that we, JOHN A. JAMES and DAVID J Anus, citizens of theUnited States, residing` at Coffeyville, in the county of Montgomery andState of Kansas, have invented certain new and useful Improvements inRegisters for Grain-Measurers, of which the following is aspecification, reference being had therein to the accompanying drawings.

Ourinvention relates to an improvement in registers for grain-measurers;and it consists in the certain peculiar features of construction andarrangement of parts more fully hereinafter described, and definitelypointed out in the claims.

The object of our invention is to provide an improved automaticregistering device especially adapted for use in connection with grainmeasurers or weighers, which is very compact in its structure andprecise in its operation. This object we accomplish by the constructionillustrated in the accompanying drawings, in which like letters ofreference indicate like parts in the several views, and in which- Figurel is a front elevation showing the front of the casing removed. Fig. 2is a central vertical section. Fig. 3 is an elevation of the dial-plateand hands or pointers. Fig. et is a detail perspective of theactuatingwheels, and Fig. 5 is a detail perspective of the escapementand governing spring.

In the drawings, A represents the casing, and B the dial-plate formedeither integral therewith or separate. This dial-plate is circular andis formed with three concentric circles, in which numbers are placed,the first series running from zero to ten, the second series from ten toone hundred by tens, and the third series from one hundred to onethousand by hundreds.

C is a ratchet-disk, having an opening c in the center thereof andprovided with a hub c', on which is sleeved a hand c2. On the oppositeface of the disk and flush with the front face of one of theratchet-teeth is secured a projecting arm c3. The upper end of this armis extended outto one side, so that it will escape the arm ofthe pawlpassing over the wheel, as hereinafter described. Secured to the frontface of the disk C and sleeved on the hub is a washer c4.

Serial No. 394.919. (No model.)

D is a cog-wheel having an opening in the center thereof, in which isrigidly secured a hollow shaft d, which passes through the opening c ofthe ratchet-disk and on the end of which is sleeved a hand d of a lengthless than the hand c2. Sleeved on the shaft d, between the ratchet-diskand the cog-wheel D and secured to the latter, is a washer d2.

F. is a wheel rigidly secured on the shaft e, which is secured insuitable bearings on the front and rear of the casing. The forward endof the shaft e passes through the hollow shaft d and has secured theretoa pointer e', which is of a length less than the length of the other twopointers. This wheel E also has a washer c2 secured thereto and which issleeved on the shaft c.

e3 are pins, preferably ten in number, secured at equal intervals on theface of the wheel F., near the periphery thereof.

F is a cog-wheel, similar to the cog-wheel D and meshing with the same,secured on the shaft f, which is journaled in bearings in the front andrear of the casing. At equal intervals around the face of the wheel Fand near the periphery thereof is a series of pins f', preferably ten innumber. These pins are engaged by the projecting arm c3 of theratchet-disk, the pins e3 being in turn engaged by the projecting armfg, secured rigidly on the rear face of the cog-wheel F.

G G are suitable flat springs secured at one endto the inside of thecasing, the other ends engaging the wheels F and E at any suitablepoints, which act to prevent movement of said Wheels when they are notactuated by the operating mechanism.

H is an escapement or pawl formed with the shank 71, which extends up'through a suitable opening L in the top of the casing, and the curvedspring-arms h2 and h3. These spring-arms h2 and h3 are in the form ofWire loops, the ends of which are bent up and adapted to iit over theperiphery of the ratchet-disk C and engage the teeth thereon, as shownin Figs. l and 5. These arms are mounted in the shank, so that the lowerend of the arm h2 will be below that of the other, and the shank isplaced at a point to one side of the axis of the wheels, so that the armh2 will be in contact with one of the teeth of the ratchet-disk, whilethe other arm is below the IOO Y ratchet-tooth. It will be understoodthat the pointers, in connection with the different wheels, operatearound the dial-plate of the f front of the casing.

The operation of our improved register is as follows: The shank h of theescapement H is connected with a suitable oscillating crankarm or othermeans on the machine in con-y which push the disk down on one side andlift it up on the other side as theshank is moved up and down. Therotation of the ratchet-disk C causes the rotation of the cog- Wheel F,through theprojecting 'arm c3 and the pins f on the wheel F, with whichit engages after it hascompleted `its revolution, which in turn causesthe revolution of the cog-wheels D, with which it meshes, and the wheelE, through thetprojecting arm f2 on the wheel F, and the pin e3, thewheel E moving one space to every revolutionof the wheel F.

From the above description it will be seen that for every Vtenrevolutions of the disk C the cog-wheels D and F revolve once, and forevery ten revolutions of the cog-wheels D and F the wheel E is revolvedonce. Thus the pointer connected 'with the disk C, the cogwheel D, andthe wheel E count by units, tens, and hundreds, respectively, in theirmovement on the dial-plate.

4As described, our device registers as high as one thousand; but we wishit to be understood that it can be made to register either a larger 'orsmaller amount by slight changes in the sizes of the wheels -andarrangement of the pins. When a certain number has been registered andit is desired to commence a new series, the device has to be reset,which can be easily accomplished by removing the pawl and turning'thepointers back.

We are aware that many minor changes in the construction and arrangementof the parts of our devicecan be made and. substituted for those hereinshown and described wit-hout in theleast departing fromthe nature andprinciple of our invention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. In a register, the combination, with the casing aud dial-plate, of aratchet-disk having an openin g in the center thereof and a hub ononeside, a pointer sleeved on the hub, a projecting arm on the oppositeside of. the disk, a cogwheel having an opening in the center thereof, ahollow shaft rigidly secured in said opening and passing through theopening in the ratchet-disk, a pointer sleeved on the outer end of thehollow shaft, a wheel in the rear of the cog-wheel having an opening inthe center thereof, a shaft rigidly secured in said opening andjournaled in bearings in the front and rear of the casing, pins on thefront face of the wheel near the periphery thereof, a pointer on theouter end of the shaft, a cog-wheel below the other cog-wheel andmeshing with the same, a shaft jonrnaled in bearings in the front andrear of the casing and uponvwhich said cogf wheel is secu red, pins onthe front face of the cog-wheel near the periphery thereof, a -projectin g arm rigidly secured on the rear face of lthe cog-wheel, and apawl engaging with the teeth of the ratchet-disksubstantiallyasglescribed.

2. In a register, the combination, with the casing and dial-plate, of aregistering mechanism within the casing, consisting of a ratchetwheelformed with an arm near its periphery and a central hub, acog-wheelmounted on a hollow shaft passing through the hub onthe ratchetdisk,'aWheel in the rear of thecogwheel provided with a series of pins ou itsside, a shaft ou which the same is rigidly mounted extending through thehub and hollow shaft on the outer wheels, bearings for the shaft inthecasing, `a cog-wheel below the other cog-wheelengaging the pinson therear wheel, a vertically-movable pawl having arms engaging theoppositesides of ithe ratchetwheel, and pointers on the outer ends iofthe hub, hollow shaft, and shaft, substantially'as described.

3. In a register, the combination, with a casing, a dial-plate, andr aratchet-disk, of a pawl consisting of a verticallysmovable shank locatedto one side of the axis'of therdisk, and

curved spring-Wire arms lsecured Ain the-end of the shank, looped attheir lower ends, and extending down on opposite sides of thelratchet-disk and engaging the teeth on the same, substantially asdescribed.

In testimony whereof we affix our signatures 'in presence of twowitnesses.
